This pipc f serves to keep the water-levels of said receptacle 1) andholder-section c at the same altitude. 2 indicates the water in'said zo receptacle and tank-section; c.' The pipe f maybe provided with stop-cock f. I i I It avill'bc here noted that the lower end b of a pi pe orne'ck section 1) projects below the water-level in said receptacle 1).. :Invirt ue 2 5 of this arrangement only that amount of waten-surface represented by. the area of thecross-section of the interior of the pipe b is' exposed to the upper receptacle b, and hence the evaporating-surface exposed to said re- 3'0 ceptacl'e-b is reduced to a minimum.

'. f indicates a zigzag conveying-pipe, one

end of which projects centrally up'throu-gh the holder or tank-section c to, a point above the water-level of I the same and the other end 5 -,of which pipe taps the lower receptacle b of the generator at .a'point above its waterle.vcl.- Asshown, this pipe f is provided with a stop'-cockf and a draw-oil? cock 1, and

- is tapped bythe-stemof a pressureegage f The upper elbow of the-pipef 'is tapped by the main conveyer-pipef, which, as shown, extends through agas-meter f, and thence .to distant points where it is to be used.

As shown, this pipe f is also provided with .4 a stop-cockf.

f" indicates"au exhaust-pipe, which, as shown, taps thermain conveyer-pipe"f at a I point inward of the meter f 7 and extends to somedistantipoinnwhere it opens to the at- 0 mosphere. ,Thisfexhaust-pipe f is provided.

with a valve or stop cock f which is normally held closed by means of .a weightf" on the freeend of the lever' secured'to' said valve f". The weightf hangs 'llIIlllO-- diately over andin position to be struck-and raised by the hcadofthe movable holder or. tank-section a when said section a is. moved upward beyond its proper zone of operation.

I .Whcn thus engagcd,the valveb will be no opened, and the gas in the holder or tank will ,be discharged through the pipe f' -until the relieved pressure pern1itssaid tank-section c and weightf" to again fall and the valve f to be'againclosed. It will thus'be seen 'Lhat the device just described serves as a safety or emergency device ant cuts the tank-section c'irombeing-thrown out of posias soon as the column is restored to its norstopped.

By the means of any ordinary weights (not shown) it is obvious that the amount of gas which would be automatically contained in said tank and the pressure at which it will be held maybe varied at wilL. I .0 indicates a valved drawmfi pipe extending from the bottom ofthe stationary tanksection 0. to some suitable pointof' discharge. 0? indicates a valved exhaust-nozzlein the head or uppere'nd of the tank-section c.

04 indicates a pocket-like extension forming part of the fixed tank-section c and in commnnicatih'n therewith through'ani opening 0". 0 indicates an overflow-pipe extending from the upper portion of the pocketctto some suitable discharging-point. I I00 I07 indicates an infiowor water-supply pipe connected with some suitable source of'w'atersupplyand discharging into the pocket 0. This pipe 0 is provided with a valve c, the stem of which is provided with an extended lever or arm To the free end of this lever. c is secured the upper end of a stem c 'of a float or air-bulb c The lower end of the stem 0 works through a seat or perforation of a cross-bracket c secured vbetween the side of the sections and the side'of the pocket a". 'By this means the bulb c is held to a trueline vertical movement.

The weight of the stem c and float or bulb 0? are sufficient when suspended in the air to r I 5 move and open the VillW 0 in the inflow-pipe 0". The buoyancyof the float c is, however, such that when the water is at'its proper al-- titude and surrounds the same it will raise the arm 0 and turn and hOld the-VaIve c in its closed position. It will thus be seen that the altitude or level'of the column'of water i .in the gas-holder or storage-tank and i'nthe lower receptacle 1) of the generator will be j automatically maintained. In other words, whenever the column of water begins to lower the fioat c will fall and the valve-c .will be opened to let in a fresh supply of water, and

rnal altitudesaid float clwillhe again raised,

the valve 0 closed,,a'nd the inflow of water. Inasmuch as t-l'iedecoinposition oi the .w -I

In virtue passage, a storagc-tank-in communication connect the same at points, one above the in the gas generatin g action rapidly decreases the volume of water therein, and as it is extremely desirable that the amount and level. of the water column should be maintained uniform, itmust be obvious that the automatic device for controllin g the inflow of the water-supply is also an extremely valuable adjunct to the apparatus i .0 indicates a hand-operated stop-cock in the inflow'pipe c It indicates an ordinary bucket, which is crating-receptacle b and'adapted to catch the accumulations of lime, which may be removed from said receptacles h by first removing the screw-cap If. its is evident, by removing the b afresh supply of the granulated calcic carbid may be introduced into said receptacle Z).

The operation of the apparatus, brieflysum- -marized,.is as follows: The movable tanksection 0 being in a lowered position'will, through the intermediate controlling connection, hold the slide-valve b in its open position, thus allowing particles of the granulated calcic carbid to fall from the receptacle 1). into the receptacle 1), where its contact with thewater will cause the decompositions ready described. The gas generated in the receptacle b will flow through the pipe f and be discharged into the holder or storage-tank c a". lVhenever the pressure in this storage: tank is'raised by the inflow of generatedgas to the determined degree, it will raise the movable section 0 and slacking the flexible connection g sufficiently to permit the weight b? on the free. end of the lever Z1 to become effective to close the slide-valve Z) and stop the. precipitation of the 'calcic-carbid parti cles from the receptacle 7) into the receptacle I); By this means the granulated caicic carbid will be automatically fed in very small quantities, the fine particles of calcic carbid will be instantly decomposed on touching the water, and hence thevery instant the supply of the fine particles of calcic carbid is shut of the above action of the granulated calcic carbid the apparatus may be made extremely sensitive in its action.
